612574 (2003 QB91) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 QB91 as potentially hazardous because its orbit does not bring it close to Earth.
2003 QB91 orbits the sun every 90,700 days (248.32 years), coming as close as 32.11 AU and reaching as far as 46.89 AU from the sun. Based on its brightness and the way it reflects light, 2003 QB91 is probably between 119.277 to 266.710 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of New Jersey.
2003 QB91's orbit is 31.10 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2003 QB91's orbit is determined by observations dating back to Aug. 24, 2003. It was last officially observed on Sept. 14, 2018. The IAU Minor Planet Center records 72 observations used to determine its orbit.
